Documents and notes decision
Coda
A capable engineer can build a useful single-tenant subset (docs+tables+AI+basic automations) in about a week, but matching Coda’s enterprise features, deep integrations, real-time collaboration, and polished templates is substantially more work and likely not worth reimplementing for most teams.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Coda alternatives, with the arithmetic →
What a replacement has to do
- Create and edit rich documents that include tables with formulas, invoke an AI assistant to generate or summarize content, and wire basic automations/integrations to external tools.
What it still won’t have
- Real-time multi-user operational transform / collaborative cursors
- Enterprise admin controls, SSO, audit logs and compliance tooling
- The full catalog of 600+ native integrations and Pack Studio
- Polished templates gallery and onboarding flows at Coda scale
- Scale, reliability, and performance optimizations of a mature SaaS
What remains hard

Runnable build prompt
Build a single-tenant Coda-like mini workspace using Next.js (React) frontend, Postgres, and a Node.js API. Implement: (1) persistent rich-text documents and tables stored in Postgres; (2) a React table view with basic row CRUD and column formulas evaluated server-side; (3) an AI assistant endpoint wired to OpenAI-compatible API for chat, summarize, and adding rows; (4) auth with email+password and per-doc access controls; (5) simple webhook connectors for inbound/outbound integrations; include error handling, unit and integration tests, and Docker Compose for local dev. Out of scope: real-time OT/CRDT collaboration, enterprise SSO, extensive integrations catalog, and multi-region scaling.

- 5 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
